This is an excellent, thorough book on the purity system of The Church of Jesus Christ of Latter-day Saints and the excommunications of the “September Six” and many others for their violations of that purity system. I bought the book out of personal interest, but I think it will be professionally valuable as well. I knew much of what was in the book, but what I didn’t know was important, and I am grateful for the volume and hope that many will read it to learn about this important period in Mormon history.

When I took a job at the University of Kentucky, a former professor (and boss) of mine at BYU told me to look up a specific French professor on campus, whom she’d also taught (and supervised) some time earlier. I ran into him several months later at a stake conference (this was, obviously, when I was still attending Latter-day Saint meetings), and we bonded over what it was like to work under our boss.
